I recently replaced the intake plenum, fuel injector assembly, and the fuel pressure regulator. Prior to the replacement the car never ran hot. Now it starts getting hot at long traffic lights. While driving home at an exceptionally long light I began hearing a steady knock coming from what sounded like deep in the engine- it did not change in tempo with the rpm's - it remained steay. I changed the oil this morning with 10w-40. The knocking came back - the following codes come up P020 P070 B132 R034. Have I cooked a main bearing or something?? HELP!!! How does this relate to the TPS errors?

I can't for the life of me, think of what would cause a knock that would not change tempo with RPM.

I should point out that when traveling to the next light it cools down and the knock goes away. I didn't know if the TPS could cause it be getting to much fuel or idling improperly so as too cause an overheating issue.
